Disabling tab discarding in Google Chrome

I had the same problem and finally found a flag named “automatic-tab-discarding” (chrome://flags/#automatic-tab-discarding). So I think the previous flag “enable-tab-discarding” has simply been renamed once the tab discarding behavior was made the default. Which makes sense.

I'd really prefer it to be a regular Chrome option though, instead of an unguaranteed-to-remain-functional flag.
